What is the Google APIs Discovery Service?
You can use the Google APIs Discovery Service to build client libraries, IDE plugins and other tools that interact with these APIs. It provides a lightweight, JSON-based API that exposes machine-readable metadata about Google APIs including:
- A directory of supported APIs.
- A machine-readable "Discovery document" for each of the supported APIs that includes:
- A list of API resource schemas based on JSON Schema.
- A list of API methods and available parameters for each method.
- A list of available OAuth 2.0 scopes.
- Inline documentation of methods, parameters and available parameter values.
Who's using it?
Google has already built a number of tools using the service:
- Google APIs client libraries - Client libraries in various languages for accessing Google APIs.
- Google APIs Explorer - An interactive web-based tool for exploring Google APIs.
- Google API Support in Google Plugin for Eclipse - An IDE integration that allows to import Google APIs support directly into your Eclipse project.
These are great examples to look at when you write custom tools and client libraries of your own.
